Abstract

See full text

The invention discloses a method for correcting differential pressure values of a fire extinguishing agent concentration analyzer in the engine compartment of an aircraft, the analyzer, and a readable storage media thereof. The method includes: correcting theoretical differential pressure values of the analyzer; measuring actual differential pressure values of the analyzer under different pressure; obtaining a series of corrected viscosity coefficients accordingly; obtaining a relation accordingly; setting a corrected model to replace the original model of the analyzer. It is solved for the problem that the noise influence caused by the pressure of flight environment cannot be overcome in the test of extinguishing agent concentration in aircraft engine compartment.
